多篇帖子讨论AI模型性能和基础设施成本

一系列Mastodon帖子讨论了AI的基础设施和性能。其中一个帖子详细介绍了MCP搜索服务的成本,估计个人使用每月为7美元,而双区域Azure方案的报价为8,400美元。另一篇帖子强调了检索增强生成(RAG)系统的一个局限性,即可能找到正确的页面,但错过了具体的答案块,导致模型表示不知道。第三篇帖子比较了不同AI模型的准确性,认为路由策略和模型大小(特别是Laya、Kev-4B和GPT-5.4 nano)对性能有显著影响,其中一个模型将许多请求错误地归类为范围之外。 AI

影响 这些讨论突显了AI基础设施潜在的成本效益,并揭示了当前RAG和模型路由策略的局限性,指出了未来AI发展的方向。

    The same MCP search service: about US$7 a month as I run it (one warm Container App, 100,000 searches), about US$8,400 as a two-region Azure proposal (running standby, 1M searches, 100 GB of content; modeled, not deployed). Traffic explains little of it. https:// pournasserian.co…

    A RAG index can return the right page and still miss the chunk with the answer. In my test, 49 of 50 questions had the right page in the top 5. One of them had the answer chunk at rank 6; the generator said "I don't know". The four layers and the code: https:// pournasserian.com/…
